Official Correct Choice:
Option C: Resistance is divided
Concept:

A potential divider (voltage divider) reduces an input voltage to a smaller output voltage using resistors in series.

Solution:

  • By placing resistors in series, the total resistance is divided into segments.


  • The total voltage drops across each segment proportionally according to \( V = IR \).


  • Hence, a potential divider is fundamentally created by dividing the resistance across the circuit path.


Why other options are incorrect:

  • Opt A: Current divides in parallel circuits, not series voltage dividers.


  • Opt B: The EMF source itself is not physically divided.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
